From 707ced0d718e89b52b13aa55a64653083e792cca Mon Sep 17 00:00:00 2001 From: Atsushi Nemoto Date: Tue, 7 Mar 2006 21:55:28 -0800 Subject: [PATCH] __get_unaligned() gcc-4 fix If the 'ptr' is a const, this code cause "assignment of read-only variable" error on gcc 4.x. Use __u64 instead of __typeof__(*(ptr)) for temporary variable to get rid of errors on gcc 4.x.
